AFAIK, CIFS has inodes where available.

Again I refuse to reintroduce a currently finely fixed bug in the file 
system support just because some other component is broken-by-design or 
under-implemented.

You cannot rely on the user being clever. The default settings (and 
preferably the non-default settings) have to be safe. Previously, the 
default browsing mode was "expand", and infinite recursion was prevented 
by device and inode matching. "none" mode was intrinsically safe. And 
"collapse" mode was not safe but at least it was not the default.

Your patch series effectively enforces the "collapse" mode and removes 
the other two. Then the playlist code will merrily expand all nodes 
recursively at it iterates them. You need to solve this before your 
patch series is merged.
